SETFILETIMEQQ

Portability Function: Sets the modification time for a specified file.

Module

USE IFPORT

result = SETFILETIMEQQ (filename,timedate)

filename

(Input) Character*(*). Name of a file.

timedate

(Input) INTEGER(4). Time and date information, as packed by PACKTIMEQQ.

Results

The result type is LOGICAL(4). The result is .TRUE. if successful; otherwise, .FALSE..

The modification time is the time the file was last modified and is useful for keeping track of different versions of the file. The process that calls SETFILETIMEQQ must have write access to the file; otherwise, the time cannot be changed. If you set timedate to FILE$CURTIME (defined in IFPORT.F90), SETFILETIMEQQ sets the modification time to the current system time.

If the function fails, call GETLASTERRORQQ to determine the reason. It can be one of the following:

Example

 USE IFPORT
 INTEGER(2) day, month, year
 INTEGER(2) hour, minute, second, hund
 INTEGER(4) timedate
 LOGICAL(4) result

 CALL GETDAT(year, month, day)
 CALL GETTIM(hour, minute, second, hund)
 CALL PACKTIMEQQ (timedate, year, month, day,    &
                  hour, minute, second)
 result = SETFILETIMEQQ('myfile.dat', timedate)
 END
